What is Vit D Powder?
Vit D Powder is a steroid hormone derived from cholesterol. There are five forms in nature, among which vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol) mainly affect human health. Of these, vitamin D3 (cholecalciferol) is the natural form of vitamin D produced in the skin from 7-dehydrocholesterol. Upon exposure to UV light, 7-dehydrocholesterol produces a vitamin D3 precursor that undergoes a temperature-sensitive rearrangement of three double bonds to form vitamin D3.
